Can

ABSTRACT

A can has a main body, an upper casing disposed on a top portion of the main body, a retained cap disposed on the upper casing, a connection ring disposed on the retained cap, and a pull ring connected to the connection ring. A rivet button fastens the connection ring and the retained cap together.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a can. More particularly, the present invention relates to a can which will form a vent hole while the can is opened.

[0002] A conventional can has a retainer cap which has a rivet button to fasten the retainer cap on a cover of the conventional can. When the conventional can is opened, the retainer cap will not be detached from the conventional can entirely. Since only one opening is formed on the cover of the can while the can is opened, liquid in the can cannot flow out of the can quickly because air cannot enter the can fast. If the can is shaked before opening, bubbles will eject out of the can.

SUMMARY OF THE INVENTION

[0003] An object of the present invention is to provide a can which will form a vent hole while the can is opened so that a liquid in the can will flow outward quickly.

[0004] Another object of the present invention is to provide a can which will form a vent hole while the can is opened so that a gas in the can will flow outward from the vent hole.

[0005] Another object of the present invention is to provide a can which has a pair of guide grooves to communicate with an oblong recess and an inner periphery groove so that liquid remains on the inner periphery groove will flow into the can.

[0006] Accordingly, a can comprises a main body, an upper casing disposed on a top portion of the main body, a retained cap disposed on the upper casing, a connection ring disposed on the retained cap, and a pull ring connected to the connection ring. A rivet button fastens the connection ring and the retained cap together. The connection ring has an annular head. A snap button fastens the annular head of the connection ring and the upper casing together. The pull ring has two hinge members enclosing the annular head of the connection ring. The upper casing has two vent holes to receive the hinge members, an oblong recess, a cutting groove surrounding the retained cap, and an inner periphery groove.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Referring to FIGS. 1 to 4, a can comprises a main body 10, an upper casing 40 disposed on a top portion of the main body 10, a retained cap 14 disposed on the upper casing 40, a connection ring 20 disposed on the retained cap 14, and a pull ring 30 connected to the connection ring 20.

[0013] A rivet button 21 fastens the connection ring 20 and the retained cap 14 together.

[0014] The connection ring 20 has an annular head 23.

[0015] A snap button 24 fastens the annular head 23 of the connection ring 20 and the upper casing 40 together.

[0016] The pull ring 30 has two hinge members 31 enclosing the annular head 23 of the connection ring 20.

[0017] The upper casing 40 has two vent holes 15 to receive the hinge members 31, an oblong recess 12, a cutting groove 13 surrounding the retained cap 14, an inner periphery groove 11, a first guide groove 17 to communicate with the oblong recess 12 and the inner periphery groove 11, and a second guide groove 17 a to communicate with the oblong recess 12 and the inner periphery groove 11.

[0018] The connection ring 20 has two lateral notches 22.

[0019] Referring to FIGS. 3 and 4, the pull ring 30 is pulled upward. The connection ring 20 will be moved upward with the pull ring 30. The lateral notches 22 cut the connection ring 20 into two portions, so the annular head 23 of the connection ring 20 will move upward but the rest of the connection ring 20 will not move upward. When the user pulls the pull ring 30 with a strong force, the whole connection ring 20 will move upward.

[0020] Referring to FIG. 4, a drinking hole 16 will be formed while the retained cap 14 moves downward. Then the rivet button 21 is a fulcrum.

[0021] The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention. 

I claim:
 1. A can comprises: a main body, an upper casing disposed on a top portion of the main body, a retained cap disposed on the upper casing, a connection ring disposed on the retained cap, a pull ring connected to the connection ring, a rivet button fastening the connection ring and the retained cap together, the connection ring having an annular head, a snap button fastening the annular head of the connection ring and the upper casing together, the pull ring having two hinge members enclosing the annular head of the connection ring, and the upper casing having two vent holes to receive the hinge members, an oblong recess, a cutting groove surrounding the retained cap, and an inner periphery groove.
 2. The can as claimed in claim 1, wherein the upper casing further has a first guide groove to communicate with the oblong recess and the inner periphery groove, and a second guide groove to communicate with the oblong recess and the inner periphery groove.
 3. The can as claimed in claim 1, wherein the connection ring has two lateral notches.
